QPoint: Don't claim that QPoint[F]::dotProduct() produces length squared

Browse Source 
The documentation snippets name the result of dotProduct()
"lengthSquared", but it is just a coincidence, not the property of dot
product of two different points. Just name the result `dotProduct`
without claiming any properties.

Also fix the type of the result in the QPointF case.
